What’s the proper distance between the grow light and the plants?
This depends on both the plant and the type of light used, but there are some general rules you can follow.
First off, do the hand test — leave your hand under the light for 30 seconds at a distance where the plant will be. If the heat is too much for you, it’s too much for the plants as well. However, that’s not the best measure.
For HID lights, keep them around 12 to 20 inches away if they’re 400 to 600 watts and keep them 16 to 30 inches away if they’re over 600 watts, as a general rule.
LED lights below 200 watts are good somewhere around 15 to 20 inches away from plants. Lights up to 500 watts should be kept around 20 to 30 inches away, while lights stronger than 500 watts need to be kept 30 to 45 inches away.
Fluorescent lights are usually good at 10 to 15 inches if they’re below 400 watts, lights of around 400–600 watts need to be kept at 15 to 25 inches and lights stronger than that should be at least 20 to 30 inches away.

Tips for Choosing the Best LED Grow Lights
Some growers just want to maximize the electricity used, others care more about making the biggest yields, and some growers care most about making things easier. Here are some important tips to remember when it comes to choosing the right size grow light for your grow space:
Light footprint — Just about every grow light has a recommended light footprint, which is usually listed in the product details by the manufacturer. For example, it may say the recommended footprint is 2’x4′ for the flowering stage. That means that this light is designed to grow plants in that size space. Even more than the recommendations below, it’s highly recommended you go by the manufacturer’s recommendation first.
How to get the best yields for electricity — Some lights are more electrically efficient than others. Generally, the smaller LED grow lights (under 300w or so) run the most efficiently and get the best yields for the amount of electricity used. Fluorescent grow lights like CFLs and T5s tend to get the worst yields for the wattage. It also helps maximize efficiency by getting a smallish light for your grow space. That’s because there will be some extra light around the edges that add small but significant amounts to your yields without using any more electricity. As a bonus, it’s easier to manage heat in a space that’s somewhat bigger than necessary.
How to get the best yields for space — If you care more about maximizing yields for a particular space, it’s recommended to get the most powerful grow light your space can support. LEDs and HPS grow lights get the biggest yields for the amount of space used. Once you get to the bigger sizes (above 500W or so), typically an HPS will get better yields for the amount of space (if not necessarily the most electrically efficient). A 600W HPS grow light in a 4’x4′ grow tent is an excellent choice that costs about $800 to get set up and can produce over 20 oz per harvest. Of all the HPS lights, the 600w size is the most efficient. If you are willing to deal with a lot of heat, you can even fit a 1000W in a 4’x4′ grow space and produce 35 oz or more. When using bigger lights in a relatively small space, it becomes more important than ever to create a great exhaust system to vent heat.
True wattage — When shopping for grow lights, look for the true power draw or amount of electricity used to run the grow light. This is often found buried in the product details. The actual wattage used helps you compare different grow lights directly.
Conclusion
Every grower wants the perfect solution for his beloved growing plants. No matter he is growing one plant or many. At last, the yield per square meter is what matters. For the maximum yield, you must know the growing requirements of your Grow tent and then buy an LED grow light accordingly.
Here, I must say that LED grow lights can solve your issues by producing the best spectrum to control temperatures inside your grow tent. Hence buy only the one that is the fittest among the plethora of Grow lights.
And, I am hopeful enough that I helped you decide the most important equipment for growing plants. I know you have found your best light for a grow tent!
